The project will apply TGS’ advanced Elastic Multi-Parameter Full Waveform Inversion and depth imaging technologies to its own legacy Geostreamer Sabah multi-client 3D Phase 2 dataset, acquired in 2017. The project aims to deliver an improved dataset, utilizing a high-resolution velocity model and diffraction imaging across the Megah Field. Processing began in July 2026, with final products scheduled for April 2027.

“The Megah discovery has reinforced the exploration potential of this area, and advanced reprocessing can play an important role in reducing subsurface uncertainty,” said EVP Multi-Client David Hajovsky. “This project highlights TGS’ ability to apply leading imaging workflows where improved subsurface definition can directly support exploration and appraisal decisions.”

The reprocessed data will support more confident geological interpretation, prospect evaluation, and future appraisal well planning.
